Il contributo della fotografia aerea nella ricerca archeologica a Cartagine per la ricostruzione del paesaggio antico

The present study starts from the history of the first archaeological research in Carthage carried out in the last century through aerial photographs. Some critically revised pictures, taken before the modern urban sprawl, allow us to capture some aspects of the ancient landscape of Carthage and its territory that had not been considered or that had been underestimated. The dynamics that led to the planning of urban tissue of Carthage are therefore examined in a diachronic perspective, with a focus on the Roman age, in particular on the period of the first urban organization, up to the point of proposing an adaptation of the settlement system previously set according to the new needs of the Roman city.

Understanding Ancient Landscapes in the Venetian Plain through an Integrated Geoarchaeological and Geophysical Approach

This paper reports the results of the multidisciplinary study carried out in the SE area of Ceggia, in the eastern part of the Venetian Plain. The area has been characterized, since ancient times, by numerous morphological transformation, due to the presence of lagoon and marshes, and interested by repeated reclamation. Aerial and satellite images have identified many natural and anthropogenic traces. From a geophysical point of view, electrical resistivity tomography (ERT) combined with frequency-domain electromagnetic measurements (FDEM) can help to discriminate the spatial distribution of different buried structures in conductive systems. The electrical conductivity is, in fact, directly related to the soil moisture content. The multidisciplinary approach adopted in this context, with the results obtained thanks to the contribution of aerial and satellite images, historical cartography, archaeological survey, geophysical measurements, geomorphological characterization, and 14C dating, allow us to suggest a possible interpretation of the different traces highlighted in the studied area. This approach suggests a potentially useful and replicable methodology to study similar evidence, such as along the North Adriatic coast and in broad sectors of the Po Valley. The key issue, in this kind of system, lies, in fact, in the possibility to date and compare traces visible on the surface by remote sensing, establishing their interest from an archaeological and geomorphological point of view using an integration of field measurements. At the end of this research, the classification of the different anomalies found in this hydraulic variable context, thanks to the multidisciplinary approach here adopted, suggest new hypotheses for reading the complex history of this understudied area.

Detecting Associations between Archaeological Site Distributions and Landscape Features: A Monte Carlo Simulation Approach for the R Environment

Detecting association between archaeological sites and physical landscape elements like geological deposits, vegetation, drainage networks, or areas of modern disturbance like mines or quarries is a key goal of archaeological projects. This goal is complicated by the incomplete nature of the archaeological record, the high degree of uncertainty of typical point distribution patterns, and, in the case of deeply buried archaeological sites, the absence of reliable information about the ancient landscape itself. Standard statistical approaches may not be applicable (e.g., X2 test) or are difficult to apply correctly (regression analysis). Monte Carlo simulation, devised in the late 1940s by mathematical physicists, offers a way to approach this problem. In this paper, we apply a Monte Carlo approach to test for association between Lower and Middle Palaeolithic sites in Hampshire and Sussex, UK, and quarries recorded on historical maps. We code our approach in the popular ‘R’ software environment, describing our methods step-by-step and providing complete scripts so others can apply our method to their own cases. Association between sites and quarries is clearly shown. We suggest ways to develop the approach further, e.g., for detecting associations between sites or artefacts and remotely-sensed deposits or features, e.g., from aerial photographs or geophysical survey.

The Cenozoic deposits of the ancient landscapes of Quadrilátero Ferrífero highlands, Southeastern Brazil: Sedimentation, pedogenesis and landscape evolution

The Quadrilátero Ferrífero (QF), Southeastern Brazil, is a very important tropical highland region in the world’s geological context for its large and diverse Archean and Proterozoic rocks with great reserves of gold, iron, manganese, aluminum and industrial rocks, on a apparently stable geological structure. There, Cenozoic deposits perched on highland valleys show unclear genetic relationships with the underlying bedrock, with no apparent regional correlation. We studied five representative Cenozoic deposits (BR356, Água Limpa, Padre Domingos, Pau Branco and Casa de Pedra) on the highlands of the Serra da Moeda syncline, Western QF, to answer the question of their sedimentological origin, and investigate their pedological evolution. Field sampling was complemented by macromorphological, mineralogical and micromorphological analysis supported by X-ray diffraction (XRD), differential thermal analysis (DTA), infrared analysis (IR), scanning electron microscopy (SEM), micropobre and transmission electron microscopy (TEM). The evolution of these isolated highland deposits comprises a deep-weathered source area, a tectonic activity, besides sedimentological and pedological processes, during and after the deposition. The deposits overlie deep saprolites of Precambrian rocks (Piracicaba and Itabira Groups), representing unconformable contact. The onset of the deposition was marked by torrential, coarse colluvial and large blocks landslides into the small basins generated by reactivating tectonic events during the Oligocene, producing local grabens. These tectonic basins were filled by cohesive debris and mudflow from the adjacent and previously laterized cover, developed under the hot and humid climate in the Eocene. The cover reveals an upside-down lateritic profile where morphology and kaolinite crystal properties (values of size of coherent scattering thickness ranging from 135 Å to 162 Å) in the bottom is related to the pedolith horizons of the former lateritic cover. Later, due to climate changes (during and after the Miocene), renewed weathering on these pre-weathered sediments occurred, characterized by alternating ferruginization and Fe-losses, with the superimposed generation of new pedogenic features such as nodules, ferruginous duricrusts and mottling (redox features). In addition to demonstrating that the Brazilian platform was not stable during the Cenozoic, these deposits reveal the role of polygenetic tropical pedological processes in their formation and transformation.

SAR Sentinel 1 Imaging and Detection of Palaeo-Landscape Features in the Mediterranean Area

The use of satellite radar in landscape archaeology offers great potential for manifold applications, such as the detection of ancient landscape features and anthropogenic transformations. Compared to optical data, the use and interpretation of radar imaging for archaeological investigations is more complex, due to many reasons including that: (i) ancient landscape features and anthropogenic transformations provide subtle signals, which are (ii) often covered by noise; and, (iii) only detectable in specific soil characteristics, moisture content, vegetation phenomenology, and meteorological parameters. In this paper, we assessed the capability of SAR Sentinel 1 in the imaging and detection of palaeo-landscape features in the Mediterranean area of Tavoliere delle Puglie. For the purpose of our investigations, a significant test site (larger than 200 km2) was selected in the Foggia Province (South of Italy) as this area has been characterized for millennia by human frequentation starting from (at least) the Neolithic. The results from the Sentinel 1 (S-1) data were successfully compared with independent data sets, and the comparison clearly showed an excellent match between the S-1 based outputs and ancient anthropogenic transformations and landscape features.

Contrasting patterns of population divergence on young and old landscapes inBanksia seminuda(Proteaceae), with evidence for recognition of subspecies

AbstractOCBIL theory provides a basis for understanding of the evolution and ecology of biota on old, climatically buffered, infertile landscapes (OCBILs) worldwide. Here, we test a genetic hypothesis presented in OCBIL theory that predicts highly differentiated intraspecific population systems on OCBILs vs. more limited differentiation on young, often disturbed, fertile landscapes (YODFELs). We examined patterns of genomic and morphological divergence in Banksia seminuda across OCBILs and YODFELs in south-western Australia. We also used these data to determine whether these OCBIL and YODFEL populations represent distinct subspecific lineages, a point of previous contention among taxonomists. As hypothesized, genomic analyses based on 3466 SNP loci revealed strong structuring within B. seminuda, with high differentiation across narrow geographic scales among OCBIL populations vs. lower differentiation across much larger geographic scales among YODFEL populations. In addition, genomic and morphological divergence was found between OCBIL and YODFEL populations, providing comprehensive quantitative evidence for two subspecies. These findings have taxonomic implications for the species and provide support for OCBIL theory and its insights into the evolution, ecology and conservation of biota on ancient landscapes.

Protohistoric pastoral landscape in northern Istria revealed by airborne LiDAR: hill forts, enclosures and long linear walls in the Mali Kras plateau (southwestern Slovenia)

This paper presents the results of an international research aimed at investigating the ancient landscape of the Mali Kras plateau, a sector of northern Istria (southwestern Slovenia). The remains of two main protohistoric hill forts, Mali Kras and Socerb, and a few minor sites were already reported from this area. A cemetery, associated with Socerb hill fort, was in use between the sixth century BC and the first century AD. Airborne LiDAR remote sensing of Mali Kras plateau has allowed to identify several unknown archaeological features, ranging from approximately square features (30 × 30 m) to larger enclosures with different shapes, very long linear features and stone mounds. The elaboration and digitization of high-definition remote sensing data compared with historical cartography, field surveys, targeted small-scale excavations and thermoluminescence dating have been performed in order to decode the complex archaeological palimpsest. The square structures can be attributed to Middle-Recent Bronze Age on the basis of pottery finds. These structures are located close to natural passages from the plateau to the gulf of Trieste, in areas with low visibility and scarcity of soil, which were traditionally used for grazing activities. The other identified enclosures, some of them sharing a similar chronology, were also probably used for pastoral activities but for other purposes since their shape and size are different. Two main long drystone walls define the southeastern sector of Mali Kras plateau in correspondence of the most accessible entrance to the area. The preliminary data and comparisons with similar structures suggest these walls could correspond to protohistoric linear boundaries built to delimit grazing or agricultural areas under direct control of the nearby settlements. The enclosures identified at Mali Kras plateau, most probably connected to herding activities, and perhaps the long linear walls too, could reflect the development of new husbandry practices in the Middle-Recent Bronze Age in the karst areas of the north Adriatic hinterland, such as observed in the alpine territory.

Archaeological landscape in central northern Istria (Croatia) revealed by airborne LiDAR: from prehistoric sites to Roman centuriation

This paper presents the results of a research aimed at investigating by airborne LiDAR the ancient landscape of a sector of central northern Istria (Croatia) from prehistory to Roman times. The area, approximately corresponding to the territory of Oprtalj/Portole, is located in a strategic position just north of the mid–Mirna/Quieto river, an important waterway connecting coastal Istria with the inlands since prehistory. The elaboration of high-definition LiDAR data compared with aerial and satellite images, historical cartography and field surveys allowed us to identify unreported prehistoric and Roman features and also get detailed topographic information about already known sites. Beside a few protohistoric hill forts discovered in the past, an open-air Neolithic or Copper Age site, a probable Bronze Age burial mound and three small protohistoric fortifications have been identified. These hill forts are clustered around a north-south valley, which represents a preferential access route from the larger Mirna valley to the karst plateau north of Oprtalj/Portole. In the same plateau, small Roman buildings associated with enclosures and probable artificial ponds have been interpreted as remains of farmsteads related to small-scale herding and agricultural activities. In the southern sector of the investigated area, consisting of marls, sandstones and fertile soils, large scatters of archaeological materials sometimes associated to outcropping features are probably the remains of larger structures characterized by a well-developed agricultural economy. Particularly interesting is the identification of fossil rectilinear land division features that overlap with the cardines of Istrian centuriation. Before our study, centuriation was identified only in the territories of Porec/Parenzo and Pula/Pola, hence believed not to extend beyond the Mirna river. The new evidence revealed by LiDAR and satellite images, however, shows that a large part of central and northern Istria, between the Mirna and the Dragonja rivers, was divided by the same grid. Based on these considerations, the archaeological evidence here presented makes the Istrian peninsula one of the largest areas in the entire Roman world to have undergone a single planned land division survey.

Airborne Electromagnetic, Magnetic, and Radiometric Surveys at the German North Sea Coast Applied to Groundwater and Soil Investigations

The knowledge of the subsurface down to about one hundred meters is fundamental for a variety of economic, ecological, and geoscientific tasks, particularly in coastal zones. Marine and terrestrial processes influence coastal zones and both seawater intrusion and submarine freshwater discharges may occur. The Federal Institute for Geosciences and Natural Resources (BGR) conducted airborne geophysical surveys in the coastal region of the German Bight between 2000 and 2014. The helicopter-borne system used simultaneously collected electromagnetic (HEM), magnetic (HMG), and radiometric (HRD) data. An area of about 5900 km2 was covered with parallel flight lines at 250 m line separation and additional tie-lines at larger separations. In total, about 25,000 km of data at sampling distances of 4 m (HEM, HMG) and 40 m (HRD) were acquired. The electrical resistivity (HEM), the anomalies of the magnetic field (HMG), and the exposure rate (HRD) are the resulting geophysical parameters derived from the data. The results are displayed as maps of the geophysical parameters as well as vertical resistivity sections (only HEM). Both data and products are publicly available via BGR’s product center. The airborne geophysical results helped to outline the fresh–saline groundwater interface, freshwater lenses on islands, submarine groundwater discharges, buried tunnel valleys, mires, and ancient landscapes.

The Pre-industrial landscape in Moravia. The case study of inventory and analysis of the ancient land use structures in the Czech Republic)

The paper deals with the process of searching and inventorying of relict - so-called pre-industrial landscape - in Moravia (approximately 1/3 of the territory in the east of the Czech Republic). So far, during the inventory of pre-industrial landscape segments in Moravia, around 1,500 land use mosaic areas have been registered, surviving without significant changes since the completion of maps of the so-called stable cadastre realized in the 1830s to the present. Each of these areas with a steady mosaic has been supplemented with substantial quantitative and qualitative characteristics. This paper presents the results of geodatabase analysis of segments of the pre-industrial landscape concerning the sea elevation and morphology of the area. The results show that although numerous parts of stable ancient landscapes have been preserved at higher altitudes, they reach larger separate areas and larger aggregate areas at lower altitudes with more fertile soils. Hypotheses attempting to explain this territorial disparity are also presented in the text of the paper.

How to access ancient landscapes? Field survey and legacy data integration for research on Greek and Roman settlement patterns in Eastern Sicily

The integration of field survey data from Eastern Sicily (the Plain of Catania) with legacy data available for the region will expand our knowledge on Mediterranean ancient rural landscapes. With an extent of 430 km2, the area is a perfect case study due to its geographical characteristics and the number of archaeological projects (both excavations and surveys) carried out within it in recent decades. Indeed, combining archaeological data from earlier research projects with new survey data allows us to conduct a settlement pattern analysis of the project’s study area. Heterogenous datasets have been integrated through their implementation into a geo-database, featuring the management and integration of topographical units and archaeological entities through semantic relations. Through geospatial data analysis based on the complete gazetteer of archaeological sites (whether sherd scatters, ruins, caves dwellings, tombs or tracks), a new image of rural landscapes for this area of Eastern Sicily from the Greek Archaic to the Late Roman Age can be visualized, beyond the traditional Sicilia frumentaria narrative.

Multiscale comparison of LS factor calculation methods based on different flow direction algorithms in Susa Ancient landscape

Topography (LS factor) is one of the most important controlling factors of soil characteristics and geomorphic processes in the landscape. This study was performed in the Susa Ancient site and aimed to compare the estimation of three different LS factor calculation methods in which the catchment area was calculated based on seven types of flow direction algorithms using DEM with five spatial resolutions. For calculating the LS factor, the catchment area attribute was used to calculate the slope length based on the flow direction. Results showed that the catchment area is an entirely scale-dependent attribute and with decreasing the spatial resolution, the statistical values of catchment area increased. At high spatial resolution, the different flow direction algorithms despite the difference in the flow distribution to the neighboring cells, but the catchment area attributes calculated based on them, are statistically slightly different. By upscaling, the LS factor values calculated in Boehner and Selige and Moore et al. methods increase, whereas in Desmet and Govers method decrease and this change rate indicates that the LS factors calculated by these three methods have the lowest sensitivity to the slope length. At a same scale, the statistics of LS factors calculated based on different flow direction algorithms depicted no considerable different. The single flow direction algorithms of Rh and D8 cause to calculate the lowest mean values of LS factors at all spatial resolutions. The difference between frequency distributions of the LS factors calculated by these three methods increases with decreasing spatial resolution. The statistical analysis of this study confirms that estimating the LS factor scale and calculation method are more important than the type of flow direction algorithm.

Farmers\u2019 landslide risk perceptions and willingness for restoration and conservation of world heritage site of Honghe Hani Rice Terraces, China

The Honghe Hani Rice Terraces (China) is an ancient world heritage agricultural landscape that has been evolved in centuries as a result of farmers’ indigenous practices and knowledge. The area, however, is prone to landslides that can burden the conservation of these landscapes including their social, cultural, economic and aesthetic value. In June 2018, a landslide threatened the villages of Duosha and Mengpin affecting 138 inhabitants and the terraces structure. This event marked the need to understand how farmers coexist with these natural hazards and which are the behaviours people adopt to conserve their environment and safeguard their livelihood. Results from 125 in-person interviews showed that farmers feel threaten by landslide events derived by their personal experience, but their poor perceived preparedness and the inefficient disaster information make them more vulnerable to those events. Nevertheless, they demonstrated a desire to increase their knowledge on terraces restoration and conservation practices. This is an important signal for public authorities and practitioners that need to underpin training activities and create momentum for discussion. The demonstrated high trust in authorities’ decisions is a crucial element to pursue the objective and sustain the conservation of the terraces and the tourism economy.

Reconstructing the palaeoenvironment at the early Mesolithic site of Lake Duvensee: Ground-penetrating radar and geoarchaeology for 3D facies mapping

We investigate the landscape development of the early Mesolithic hunter-gatherer sites of Duvensee (10000–6500 cal. BCE). Based on ground-penetrating radar (GPR) and geoarchaeological drillings, we present for the first time a three-dimensional (3D) reconstruction of the palaeoenvironment of 63 ha covering subarea of the former lake during the Mesolithic. The archaeological aims were (1) to detect the location of former islands possibly hosting hunter-gatherer settlements and (2) to reconstruct the ancient landscape development for understanding prehistoric land use. The research in Duvensee lasts almost 100 years, providing vivid illustrations of early Mesolithic life. Clusters of Mesolithic camps have been found located on small sand hills that formed islands in the prehistoric lake. For this environment, we present depth maps of the three most important sedimentary facies interfaces of the ancient Lake Duvensee. Interface1 represents the transition between coarse organic sediments (peat and coarse detritus gyttja) and fine-grained organic sediments (fine detritus gyttja, calcareous gyttja), Interface2 represents the transition to the underlying clayish-loamy sediments, and Interface3 marks the top of the basal sand deposits at the lake bottom. From Interface3, we identified the location and extent of five former islands with Mesolithic camps. Stratigraphic information from the corings enabled us to create a 3D model of the spatio-temporal development of the Duvensee bog. The locations of the islands and their estimated dive-up times agree with the spatio-temporal pattern of the previous archaeological finds. The model shows where hunter-gatherers could settle and move from one island to another following the shorelines of the overgrowing lake. The 3D stratigraphic model provides growth and shrinking rates of the island and lake areas in the Mesolithic, and volumes of organic and non-organic deposited lake sediments. Besides, it provides a basis for a sustainable groundwater management needed for heritage preservation.

‘Semi‐dwarf’ woolly mammoths from the East Siberian Sea coast, continental Russia

A pioneer comprehensive study of several diminutive last‐generation woolly mammoth teeth (M3) found on the coast of the East Siberian Sea between the mouths of the Alazeya and Malaya Kuropatoch'ya rivers was conducted. Two teeth belonged to one individual. These teeth have a similar lamellar frequency and enamel thickness as teeth of Mammuthus primigenius Blumenbach. The molar crowns from the lower Alazeya region are similar in size to those of the small Late Pleistocene–Holocene mammoths from Wrangel Island. However, the number of plates (17–19, excluding talons) is much lower than that in the teeth of typical Late Pleistocene M. primigenius (23–25). The age data of the examined teeth are beyond the limits of the 14C dating method (>45 000 years BP). Nevertheless, palaeobotanical data allow correlation of the enclosing sediments with the warm Kazantsevo Interglacial (Eemian, MIS 5e) and reconstruction of the average annual temperature, which was warmer than present‐day temperatures. These conditions are confirmed by the δ18O isotopes from the structurally bound carbonate in tooth enamel. The ancient landscape was wetter and more forested than modern landscapes. The diminution of M3 size and loss of posterior plates were a result of the overall decrease in body size, likely in response to landscape change and narrowing of resource space. Mammoths from the lower Alazeya region demonstrate a stage of significant size reduction, although the dwarfing was not finalized. Their teeth are the oldest amongst the small teeth found in west Beringia.

Europe's lost frontier

Aided by dedicated amateurs and new methods, scientists reconstruct a now-submerged ancient landscape—and the people who lived there.

Between Land and Sea: Tell Mirhan and the Chekka Regional Survey

In 2016 the Institute for Oriental and European Archaeology (OREA) and the Department for History and Archaeology at the American University of Beirut (AUB) launched a new archaeological project in the Chekka region in Lebanon. The Chekka region borders the shore of the Mediterranean and is situated between Batroun in the south and Tripoli in the north. At the northern end of the modern town of Chekka directly at the seashore one finds the remains of Tell Mirhan on the premises of a modern cement factory (Fig. 1). This tell and its hinterland have never been the subject of a thorough and systematic archaeological investigation. A survey conducted at Tell Mirhan in 2016 and an excavation in 2018 revealed an early Iron Age occupation (1200– 700BC) superimposing a massive rampart fortification of the Middle Bronze Age. Egyptian pottery from the Middle and New Kingdom as well as imports from Cyprus and Greece testify to the importance of this site as a harbour town during these periods. In order to investigate the site’s relation with its hinterland, a survey of the region from the coast into the foothills of Mount Lebanon was launched. To cope with a rather difficult terrain and intensive modern construction activities and changes of the ancient landscape, we conducted a LiDAR scan of the survey area in November of 2018.

Namtso Ancient Lagoon and Ancient Sea Erosion Landform

During a certain geological period, the sea surface is at the current elevation of about 4746-4755 meters. When the sea surface is about 4746-4755 meters above sea level, the Namtso region of Tibet is a lagoon in the sea. The sea surface was kept stable at the above location for a long time, and a lot of sea erosion landforms were generated on the coast. The ancient sea erosion caves, sea erosion pillars, sea erosion arch bridges, sea erosion headlands, sea erosion headlands, sea erosion cliffs, sea erosion platforms and other various ancient sea erosion micro-landforms are well preserved on the banks of Namtso Lake. It is a unique and natural ancient coastal landscape park in the world

Wilderness in Ancient Chinese Landscape Painting

Chinese painting is dominated by landscape painting, which is a unique form of artistic expression for Chinese people, while landscape generally refers to nature. Wild natural landscape can be called “wilderness,” which embodies the vitality and upward vitality of nature, and also contains unique cultural characteristics. “Wilderness” is the most important “original ecological” environment in the natural environment. Its existence has natural, ecological, and aesthetic significance. It is nature in its primitiveness and ecology in its wildness; the aesthetic lives on in it. Compared with Western landscape painting, it pays particular attention to realism, good at depicting beautiful natural scenery and recording the reality of scenery. On the other hand, Chinese landscape painting pays more attention to the expression of connotation. Chinese landscape painting focuses on nature, takes meaning as its purpose and pursues culture. Chinese landscape painting is the outstanding expression of wilderness spirit, which is mainly manifested in three aspects: (1) Chinese landscape painting is of the same origin as “Tao” (道); (2) the “wilderness” in landscape painting has a strong vitality; (3) “wilderness” has a special cultural connotation. China’s wilderness is not ecological, but is vibrant; not in the dust, but out of the dust; not in nature, but in culture.
